Abstract (en)

[origin: EP0578171A2] In a slide fastener coupling element forming apparatus, a blank wire (W) of a generally Y-shape cross section intermittently supplied at a predetermined pitch is cut off into successive pieces of a predetermined thickness by a fixed cutting punch 19 and a reciprocating cutting die (3), and then a bulge for the head portion of a coupling element is formed by a forming die 4 and a forming punch (17) movable upwardly and downwardly to coact with the forming die (4). The forming die (4) is located to be connected with the forward end in the stroke direction of the cutting die (19), and the forming punch (17) is located upwardly of the bulge forming station. Then the opposite leg portions of a coupling element are pushed out of the mold of the forming die (4) by a vertically movable ejector pin (5) located under the leg portions on the forming die (4) to discharge the formed coupling element from the forming die (4). <IMAGE>
